A disc of radius `10 cm` rotates in `XY` plane about an axis passing through its centre and perpendicular to the plane. At a particlular moment a point A on the disc has an acceleration `vec a_(A) = - 6 hat I m//s^(2)`.
The linear acceleration of point `B` on disc is :
A. `6 hat i m//s^(2)`
B. `- 6 hat i m//s^(2)`
C. `6 hat j m//s^(2)`
D. `- 6 hat j m//s^(2)`
